suspect-devices/circuitpython/cc3200/simplelink, branch 1.x CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=1.x 2016-06-28T10:28:53+00:00 cc3200: Shrink the FreeRTOS heap and place TCB+stack in freed location. 2016-06-28T10:28:53+00:00 Damien George damien.p.george@gmail.com 2016-06-05T12:01:16+00:00 urn:sha1:469c623bb8e504ca78f1964508579ecefec76a98 The 16k FreeRTOS heap originally had all TCBs and stacks dynamically allocated within it (plus semaphores and some other things). Now that xTaskCreateStatic is used instead of xTaskCreate, the TCBs and stacks are allocated statically and no longer use any of the FreeRTOS heap. Therefore, the FreeRTOS stack can be shrunk by the amount that has been made static. Furthermore, the TCBs and stack that are now static should be placed in the .rtos_heaps section of RAM because this RAM is treated specially by the bootloader (the bootloader executes from the first 16k of RAM and loads the firmware into the section starting after the 16k). After this patch the FreeRTOS heap (ucHeap) is 7200 bytes. The memory available for the MicroPython heap is 54936 bytes (including GC overhead). cc3200: Start the simplelink spawn task using the static task creator. 2016-06-28T10:28:53+00:00 Damien George damien.p.george@gmail.com 2016-06-05T11:57:18+00:00 urn:sha1:e098eac19552a5a399ffbfae44e4b329ca623d0d In VStartSimpleLinkSpawnTask we change xTaskCreate to xTaskCreateStatic so that the task is created using statically allocated memory for the TCB and stack. This means that xTaskCreate function is no longer needed (the static version is now used exclusively). cc3200: Remove .boot section attribute from osi_TaskCreate function. 2016-06-28T10:28:53+00:00 Damien George damien.p.george@gmail.com 2016-06-05T11:45:37+00:00 urn:sha1:5b8e884573d582d2c48c7b344a8876fbbeb67692 This function is no longer used. Having the .boot section attribute meant that it was included in the firmware regargless of use. Without this attribute the linker can remove the function. cc3200: Remove includes of rom.h (must be included via rom_map.h). 2015-11-01T22:33:12+00:00 danicampora daniel@wipy.io 2015-11-01T22:17:28+00:00 urn:sha1:056cb288d9a3d5aa35b3cf549f88688b9ba60163 cc3200: Increase stack sizes a bit. 2015-10-19T19:17:15+00:00 danicampora daniel@wipy.io 2015-10-19T09:41:04+00:00 urn:sha1:65f6324573db77a35152d09642b1f3e26eed3908 cc3200: Remove unneeded SPI instruction in the simplelink driver. 2015-03-26T19:50:39+00:00 Daniel Campora daniel@wipy.io 2015-03-26T19:47:51+00:00 urn:sha1:1eba62cac9473b69712effb3fa30bb3f9f9b6b1b Setting the word count before a SPI transaction is only needed when using DMA. cc3200: Update simplelink SPI driver to SDK release version 1.1.0. 2015-03-15T23:42:06+00:00 danicampora danicampora@gmail.com 2015-03-15T09:19:13+00:00 urn:sha1:c292632b5969301d1328c66f38be4ddde40b4c62 cc3200: Reduce stack sizes of simplelink and the servers. 2015-03-11T21:09:51+00:00 danicampora danicampora@gmail.com 2015-03-11T20:26:15+00:00 urn:sha1:db0580d0a5cb8caa0b3f3a0e86879ddb1a9260ff cc3200: Add power management framework.

Now they are placed in a special section named "boot" which sits just before the heap, allowing us to extend the effective heap area up to the new boot section. Right now, this gives us back ~1K, but in the future, more functions might end up in there as well.
